Throne and Liberty Update 4.15.0 Rebalances Weapons and Buffs Set Bonuses

What changed#

Update 4.15.0 for Throne and Liberty brings targeted combat rebalancing, stat calculation adjustments, and new avenues for acquiring trait materials. Server downtime begins October 7 at 10<30> p.m. PT (5<30> a.m. UTC) and is expected to last roughly three hours.

The update introduces several key changes across combat and progression systems:

• Lucky Reward Chests & Guild Loot: Defeating Vegamor now awards Unique Heroic Trait Enchantment Stones via Lucky Reward Chests granted randomly to participants (these chests are excluded from Guild Distribution). Additionally, guilds can now register 11 Amitoi, 11 Shapeshifts, Chaos Prisms, and Snow Flowers dropped by bosses into Guild Distribution.
• Trait Resonance Adjustments: Players can now craft Trait Resonance Stones directly using 6 Trait Resonance Stone Pieces, 25 Precious Magic Powder, and 30,000 Sollant. Trait Resonance enhancement success rates have also been increased.
• Weapon Potential Ability Nerfs: Cooldown reductions granted by Potential Abilities have been reduced across almost every weapon category:
  • Sword and Shield: 6 seconds down to 4 seconds
  • Daggers: 9 seconds down to 5 seconds
  • Longbow: 10 seconds down to 8 seconds
  • Wand: 9 seconds down to 6 seconds
  • Spear: 10 seconds down to 8 seconds
  • Orb: 30 seconds down to 20 seconds
  • Gauntlets: 25% down to 15%
• Skill Core and Ability Rebalances: Dagger skills saw significant shifts; Venomous Swamp’s monster damage increase fell from 80% to 15%, while Creeping Death’s Venomous Edge chance rose to 12%. Longbow capabilities were adjusted toward group play, boosting party-based sustained healing from 2.5% to 3% per member and expanding Distorted Sanctuary’s Legendary Lv. 5 attack range bonus per member to 1.1%.
• Armor Set Buffs: Two-piece set bonuses received increases. Black Lament Dawn and Ashen Oath Brand both saw Critical Hit Damage rise from 15% to 17%, alongside PvP critical stat increases per 10 Fortitude or Dexterity moving from 30 to 36. Returned Lord and Frost Lord Black Scale two-piece Heavy Attack Damage increased from 20% to 22%.
• Tower of Greed Season Ends: The current season of Tower of Greed has concluded, disabling matchmaking and locking the Extra Codex until the next season starts.

Why it matters#

Weapon Potential Abilities have undergone substantial tuning, meaning builds reliant on rapid skill cycling will experience longer downtime between ability uses. Dagger users face a sharp reduction in PvE damage amplification through Venomous Swamp, shifting reliance toward alternative Skill Cores.

On the progression front, direct crafting recipes for Trait Resonance Stones give players a deterministic method to advance gear stats without depending solely on random upgrade rolls. Combined with set bonus upgrades for Critical Hit and Heavy Attack Damage, high-end gearing offers higher offensive caps.

What to do next#

Plan around the scheduled maintenance on October 7 at 10<30> p.m. PT (5<30> a.m. UTC). Players looking to craft Trait Resonance Stones post-patch should stockpile 6 Trait Resonance Stone Pieces, 25 Precious Magic Powder, and 30,000 Sollant per stone. Those running Black Lament Dawn, Ashen Oath Brand, Returned Lord, or Frost Lord Black Scale armors should re-evaluate their stat totals to take advantage of the updated two-piece bonuses.
